To aZZ whom it may concern: ing the journal 12 to provide for dismounting Be it known that I, DAVID M.

groove 15, which is engaged byaholding-web The receptacle 7 has a cover 37, provided 16, carried by a sleeve or collar 17, fitted on on its lower face with a socket 38 and fitted the vertical arm of the bracket 14. The deat its upper end therein and at its lower end pending web 16 is provided in its lower end in a socket 39. On the bottom of the receptoo with a curved notch or recess fitting in the antacle is a dasher-stem e0, carrying perforated nular groove 15, thereby detachably mountelliptical plates 41. As the receptacle is rotated its contents are thrown from one end to the other, against the dasher-plates, and through suitable perforations therein. The cover 37 is provided with a depending flange to fit within the body and packing 42, of rubber or any suitable material for forming a tightjoint. The cover of the receptacle is provided upon its exterior surface with an oppositely-bevelcd wedge 43, with which cooperate swinging bails l6 and 47, pivoted to the sides of the receptacle and adapted at their looped ends to traverse, respectively, the oppositely-inclined edges of the wedge. As the looped ends of the bails are drawn toward each other and slide upward upon said inclined edges the downward pressure upon the cover is increased, and in order to hold the bails at the desired adjustment I employ retainingrods 48. These rods are constructed to slide at their opposite ends upon the bails, respectively, and they are arranged approximately parallel with the-wedge-block. The pivotal ends of the bails are arranged at such an interval that the sides of thebails incline inwardly or toward each other toward their upper ends or toward their looped portions, and hence in order to increase the pressure on the cover the retaining-rods may be drawn outwardly or from each other toward the pivotal points of the bails. This movement has the effect of forcing the looped ends of the bails inward or toward each other, and hence nearer to the center of the wedge-block.

In practice I prefer to provide one of the inclined faces of the wedge-block with rounded depressions or corrugations 45 for engagement with one of the bails, said corrugations being designed solely to steady the engaged bail, and hence, through the retaining-rods, prevent vibration of either rod. These corrugations do not serve to lock the engaged bail against outward movement, as this is ob jectionable from the fact that theywould interfere with the release and removal of the cover when desired. The retaining-rods are preferably provided at one end with an eye 49, which is permanently engagedwith the bail 4G, and at the other end with an open eye or hook to engage the bail 47, said open eye or hook being adapted .to be disengaged to allow the removal of the bails from contact with the surfaces of the wedge-block.

Various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the spirit or sacrificing any of the advantages of this invention. v

Having described my invention, what I claim is- 1. The combination with a receptacle having a removable cover, of an oppositely-beveled exterior wed ge-block carried by the cover, and having its faces inclined downward from a common central apex, bails pivoted at their extremities to the sides of the receptacle approximately opposite the ends of the block and adapted to swing toward and from each other at their looped ends said bails being inclined toward each other when their looped ends are in engagement with the faces of the wedge-block, holding-rods fitted terminally to slide upon the bails, respectively, upon opposite sides of and parallel with the wedgeblock, whereby as the holding-rods are moved from the wedge-block or toward the pivotal points of the bails the looped portions of the bails are drawn toward each other to exert downward spring-pressure upon the wedgeblock, substantially as specified.

2. The combination with a receptacle having a removable cover, of a beveled wedgeblock carried by the cover and having its faces inclined downward from a central apex, bails pivotally mounted upon the sides of the receptacle and adapted at their looped ends to traverse, respectively, the inclined faces of the wedge-block, said bails being inclined inward or toward each other when their looped ends are in engagement with the wedgeblock, and retaining-rods connecting and being mounted to slide upon the bails upon opposite sides of and parallel with the wedgeblock to hold the looped ends of the bails in engagement with the wedge -block and to draw said looped ends inward as the rods are slid outwardly or from each other, each holding-rod being provided at one end with a closed eye which is permanently mounted upon one of the bails and at the other end with an open eye or hook for temporary engagement with the other bail, whereby the bails may be disconnected, substantially as specified.

3. The combination with a receptacle having a removable cover, of a beveled wedgeblock carried by the cover and having its faces inclined in opposite directions from a central apex, bails pivoted to the sides of the receptacle and adapted at their looped ends to traverse the respect-ively-inclined faces of the wedge-block, said bails being inclined toward each other when their looped ends are in engagement with the wedge-block and holding-rods terminally mounted to slide upon the bails parallel with and upon opposite sides of the block to hold the looped ends of the bails in operative relation with the inclined faces of the wedge-block and draw them upwardly thereon as the holding-rods are moved outwardly or from the wed geblock, one of said inclined faces being provided with rounded depressions or corrugations 4:5 to receive the looped end of one of the bails, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

DAVID M. BUERK.
